I have two processes that I need to keep running. The first process is a server, the second is basically a canvas for creating images which get saved to a directory. So I plan on using launchd (Mac OS 10.5) on a server to check every minute or so to make sure two things are true:
1) Both apps are running.
2) Neither app is hanging (I can do this by checking the image directory to make sure time stamps of certain files aren't more than an hour old)
I also want to just reboot the whole thing once per day at midnight.
Last time I used perl was about 10 years ago so I really need some help. Here's what I'd like to do in a pseudo code format:

Hi Guys,
Monitoring 'Total Processes' on Linux servers has been always something you 'should' do.
My question is - why? Is it relevant anymore?
If you monitor memory and cpu params, you have a pretty good idea about what's going on.
Is the number of processes really matter?
Thanks (1 Reply)

plack::handler
Plack::Handler(3pm) User Contributed Perl Documentation Plack::Handler(3pm)NAME
Plack::Handler - Connects PSGI applications and Web servers
SYNOPSIS
package Plack::Handler::AwesomeWebServer;
sub new {
my($class, %opt) = @_;
...
return $self;
}
sub run {
my($self, $app) = @_;
# launch the AwesomeWebServer and run $app in the loop
}
# then from command line
plackup -s AwesomeWebServer -a app.psgi
DESCRIPTION
Plack::Handler defines an adapter (connector) interface to adapt plackup and Plack::Runner to various PSGI web servers, such as Apache2 for
mod_perl and Standalone for HTTP::Server::PSGI.
It is an empty class, and as long as they implement the methods defined as an Server adapter interface, they do not need to inherit
Plack::Handler.
If you write a new handler for existing web servers, I recommend you to include the full name of the server module after Plack::Handler
prefix, like Plack::Handler::Net::Server::Coro if you write a handler for Net::Server::Coro. That way you'll be using plackup command line
option like:
plackup -s Net::Server::Coro
that makes it easy to figure out which web server you're going to use.
METHODS
new
$server = FooBarServer->new(%args);
Creates a new adapter object. %args can take arbitrary parameters to configure server environments but common parameters are:
port Port number the server listens to.
host Address the server listens to. Set to undef to listen any interface.
run
$server->run($app);
Starts the server process and when a request comes in, run the PSGI application passed in $app in the loop.
register_service
$server->register_service($app);
Optional interface if your server should run in parallel with other event loop, particularly AnyEvent. This is the same as "run" but
doesn't run the main loop.
